Being barefoot is considered unhygienic, and in public it is an extreme taboo.
The threat of epidemic disease lurks in unhygienic, crowded camps and back in villages where putrefying animals lie under the mud and in pools of stagnant water.
I would like to call it one of the most unhygienic areas in the world.
It's unhygienic and unhealthy, particularly if you spit close to other people.
